Subject: [PATCH 1/5] x86/PCI: Mark DMI tables as initialization data
Date: Mon, 25 Aug 2014 23:26:35 +0200 [thread overview]
Message-ID: <1409001999-23161-2-git-send-email-minipli@googlemail.com> (raw)
In-Reply-To: <1409001999-23161-1-git-send-email-minipli@googlemail.com>
The DMI tables are only used in __init code, thereby can be marked as
initialization data, too. The same is true for the callback functions
referenced from the DMI tables.
This moves ~9.6 kB of code and r/o data to the init sections, marking
the memory for release after initialization.
